LED in 2013, still a hot topic
Singapore 10th January 2013
LED is still a hot topic in 2013 that’s for sure. I was forwarded an article written by Annette Kelso published in LED Magazine of December 2012 which I have used to write this blog. In this article she describes the challenges of two worlds that are trying to unite to one LED world. We have the more than a century old lighting industry world with its conventional approach to lighting on one side and on the other we have the fast evolving semiconductor industry world from where the LED technology has emerged. The two however have totally different speeds of evolution!
In the conventional lighting world the traditional speed of innovation, research and development for a new lighting product has always been typically 2 years or so, from concept to commercial production. But in the semiconductor world developments are fast paced with very short product cycles, with new models emerging every few months! It is therefore not surprising that the lighting manufacturers have a hard time to keep up the pace in incorporating the continuously developing LED technology into their lighting fixtures. This explains to me also why many of the LED products in the market do not seem to be totally out-developed, many still having little hitches and stiches! Against this context it starts to make sense. The lighting manufacturers struggle to keep up with the technology LED innovations!
As a result we also face a big technology push, rather than a market driven demand! While that works to a certain extent in the retail market, it certainly does not in the professional project market! It is also appears that the behaviour that determines our lighting world, our common lighting standards, lighting design approaches and decisions are still very much driven by the same (emotional) principles as before. Today light fittings with LED technology are still very much the same as it was (still is) for conventional lighting technology. Emotional considerations such as colour temperature, colour rendering capacity, lumen packages and the like are still key decision elements in a design or purchase decision. High energy efficiency and long life are not necessarily the key for success, let alone when considering the costs!
LED is undeniably part of the future of lighting, however how the two worlds will manage to cohabit and integrate together will be the next phase of generation LED…
